DEI's database is what I use, and they are correct more times than not. Bulldog has never been right in my experience. You should always verify all wiring with a DMM PRIOR to hooking anything into the wiring. Here is what DEI lists:
DIRECTWIRE™ WIRING INFORMATION - DODGE / DURANGO / 2004 / Remote Start
[PRINT THIS PAGE]
12volts RED / org (30A), RED / blue (20A) + ignition harness
Notes: Vehicles with ATC (Automatic Temperature Control) heating and A/C systems have an extra RED / brown (40A) 12V wire, and an extra dk. blue accessory wire.
Starter pink/lt. blue + ignition harness
Second Starter N/A
Ignition pink/lt. green + ignition harness
Second Ignition pink or black + ignition harness
Third Ignition N/A
Accessory pink / YELLOW + ignition harness
Notes: Vehicles with ATC (Automatic Temperature Control) heating and A/C systems have an extra RED / brown (40A) 12V wire, and an extra dk. blue accessory wire.
Second Accessory pink/purple + ignition harness
Keysense PURPLE / tan - ignition harness
Power Lock PURPLE / dk. green - see notes
Notes: Lock is negative trigger thru a 330 ohm resistor. Unlock is negative trigger thru a 100 ohm resistor. MUST use relays.
On vehicles without memory seats, the wire can be found in the driver kick, door harness. On vehicles with memory seats, the wire is in the driver door at the DMMM (Driver Memory Mirror Module).
Power Unlock same as power lock wire
Lock Motor lt. green 5wi driver kick, door harness
Unlock Motor tan/lt. green 5wi driver kick, door harness
Parking Lights+ pink/red (L), WHITE/ orange (R) + fuse box, black plug, pins 6 and 5
Parking Lights- pink/red - headlight switch
Notes: Parking lights are negative trigger thru a 1100 ohm resistor. There is a rest resistance on the wire, so MUST use a relay to isolate away from the switch.
Hazards WHITE/ dk. blue - hazard switch
Notes: Hazards are negative trigger thru a 120 ohm resistor.
Turn Signal(L) use hazards wire
Turn Signal(R) use hazards wire
Reverse Light WHITE/ lt. green or WHITE/ red + fuse box, black plug, pin 17 or 18
Door Trigger see notes - see notes
Notes: The LF door trigger is purple, RF door is PURPLE / white, LR door is PURPLE / gray, and RR door is purple / YELLOW. Use all four wires and diode isolate each wire from each other and the control module. Refer to DirectFax 1076 for wiring information.
The rear door triggers are in a large 74 pin plug near the fuse box.
On vehicles without memory seats, the front door triggers are in the same plug as the rears. On vehicles with memory seats, the front door triggers are in the doors at the DMMM (Driver Memory Mirror Module), and PMMM (Passenger Memory Mirror Module).
Dome Supervision yellow/orange + large 74 pin plug near fuse box
Trunk/Hatch Pin PURPLE / orange - large 74 pin plug near fuse box
Hood Pin PURPLE / lt. blue - hood pin switch
Trunk/Hatch Release N/A
Power Sliding Door N/A
Factory Alarm Arm arms on lock with door open
Factory Alarm Disarm factory remote only
Disarm No Unlock with ignition and Sentry Key
Tachometer NOT red or BROWN / white ac any ignition coil or fuel injector
Wait to start N/A
Brake Wire WHITE/ tan + fuse box, black plug, pin 19
Parking Brake dk. GREEN / WHITE - parking brake switch
Horn Trigger dk. GREEN/ purple - horn switch
Memory Seat 1 lt. GREEN/ dk. blue - Driver Memory Mirror Module in door
Notes: Memory seat 1 is negative trigger thru a 7K ohm resistor. Memory seat 2 is negative trigger thru a 2K ohm resistor. MUST use relays.
Memory Seat 2 same as memory seat 1 wire -
Memory Seat 3 N/A -

As far as the reference to the gray keys go, that only applies to keys without remotes built in. You probably have a transponder. The easiest way to tell, is once you have your starter hooked up according to the above chart try remote starting, if it does not start, put a key in the ignition in the off position and try again if it starts you have a transponder. If it does not start, recheck your wiring and try again.
